Recall from the very early years of your education that addition means adding a group of numbers together. Addition is almost always signified by the + symbol.
Example: 5 + 4 = 9
Subtraction means taking the value of one number away from the value of another number. Subtraction is almost always signified by the – symbol.
Example: 8 – 4 = 4
Note that the result of an addition problem is known as the sum, and the result of a subtraction problem is known as the difference.
